Abstract: Plant extracts in powder or essential oil form from different bioactive compound producing plants are known to be effective repellents and insecticides against different storage pests of grains. Post-harvest losses are one of the major causes of food insecurity in the developing world. , the present study was planned to investigate the effect of neem and peppermint leaf powders in control of maize weevil and the prolonged storage of the powders on their insecticidal activity. A 2 �...
Abstract: Maize lethal necrosis (MLN) is a virus disease complex that was recently reported in eastern Africa. It causes huge yield losses, hence threatening food security in the region. It is caused by a co-infection of Maize chlorotic mottle virus (MCMV) and Sugarcane mosaic virus (SCMV) in maize and other cereal crops. Thrips and beetles are known vectors of MCMV while SCMV is vectored by aphids. Since MLN is new to Africa, there are no known effective management strategies against the di...
ABSTRACT Laboratory experiments were conducted in the Department of Plant protection, College of Agricultural Studies, Sudan University of Science and Technology (SUST) to evaluate the lethal effect of seed ethanolic extracts of Coffee senna Cassia occidentalis L. and Damas Concorpus lancifolius Engl. against the second larval instars of the African melon ladybird Henosepilachna elaterii Rossi. Also further experiments were conducted to investigate the efficacy of sesame oil as a synergist. ...
ABSTRACT This study was carried out to monitor and survey the fruit fly species in Slait area north of Khartoum Bahri locality, during the period from November 2017 to March 2018 to identify the major species. Hence a Survey was carried out using, the food traps (guava juice) and sticky traps (Methyl Eugenol) for capturing prevailing species in Slait area. The results of the survey showed that there are two types of fruit flies, the peach fruit fly (Bactrocera zonata), which was the dominant...

Different concentration s (5%, 10% and 20%) of each of the tested plant, in addition...
Mesquite plant [Prosopis juliflora (Swartz) DC] is an invasive, evergreen and multi-purpose leguminous tree or shrub, native to South America. Unfortunately, due to deliberate distribution within Sudan, the plant became a threat to agriculture and biodiversity. The observed absence of ground vegetation under its canopy suggests that it has some allopathic potential that may be caused by fallen fruits, leaves, roots exudates or plant leachates. The release of these allelochemicals in t0 ...
Abstract Laboratory experiments were conducted at the Department of Plant protection, College of Agricultural Studies, Sudan University of Science and Technology (SUST) to evaluate the lethal effect Bee glue powder and ethanolic extracts of leaves Neem Azadirachta indica L. ,Basil Ocimum basilicum. From each test four different concentrations were applied against adult stage of Asian fruit fly Bactrocera invadens Drew Tsuruta and White (Diptera:Tephritidae),as topical and as food bait and th...
Sorghum is considered one of the major cereal crop and staple food as well for millions of the poorest and most food insecure people in many part of the world and in Sudan as well. The production and consumption of sorghum is constrained by several factors, the most important among which are seed-borne fungal species. In addition to causing quantitative losses, these spoilage fungi produce highly toxic and carcinogenic mycotoxins. In view of the negative public health and economic impac...
